Exercise can't cure the common cold. In fact, intensely vigorous
exercise, such as running a marathon, lowers the body's ability
to fight germs. But moderately active adults may suffer fewer
colds than their more sedentary counterparts, according to
a recent study in Medicine & Science in Sports & Exercise.
The study investigated the number of common colds in more
than 500 people of varying activity levels. For one year,
researchers tracked these individuals for the number of upper-respiratory
tract infections and total moderate-vigorous levels of activity.
The most active individuals in the study suffered an average
of 23% fewer colds per year than the least active people.
In the fall, the difference was the most noticeable, with
32% less risk for a cold
in the most active group. Forty percent of all colds in this
study were reported in the fall.
Regular physical activity appears to stimulate our immune
systems to help fight off germs, which may reduce risk for
future colds. Be sure to exercise regularly, not only for
fewer colds, but to boost self-esteem and overall health.
Talk to your doctor of chiropractic about the workout that's
right for you.
